Master list of auction houses?

I'm not sure if there's one of these floating around, but it seems like at least once a month I stumble on a new auction site I haven't been involved with.

Is there one on the internet anywhere? It might be good to have one on here, and update it whenever they're having an auction going. I missed one tonight that I'm kind of annoyed with.

get on the mailing list here:

It's to much to keep up with, and where do they constantly get all this great stuff ? It seems lately that the only scarce items out there is CASH !!!!!!!!!!
